Called when importing a contract.

public:
 void ImportContract(System::ServiceModel::Description::WsdlImporter ^ importer, System::ServiceModel::Description::WsdlContractConversionContext ^ context);

public void ImportContract (System.ServiceModel.Description.WsdlImporter importer, System.ServiceModel.Description.WsdlContractConversionContext context);

abstract member ImportContract : System.ServiceModel.Description.WsdlImporter * System.ServiceModel.Description.WsdlContractConversionContext -> unit

Public Sub ImportContract (importer As WsdlImporter, context As WsdlContractConversionContext)

Parameters

importer: WsdlImporter

The importer.

context: WsdlContractConversionContext

The import context to be modified.

Examples

The following code example shows the use of IWsdlImportExtension to add an System.ServiceModel.Description.IServiceContractGenerationExtension and an System.ServiceModel.Description.IOperationContractGenerationExtension (the WsdlDocumentationImporter, in this case) to modify generated WCF client code at the interface and operation level.

  public void ImportContract(WsdlImporter importer, WsdlContractConversionContext context)
  {
Console.Write("ImportContract");
      // Contract Documentation
      if (context.WsdlPortType.Documentation != null)
      {
  context.Contract.Behaviors.Add(new WsdlDocumentationImporter(context.WsdlPortType.Documentation));
      }
      // Operation Documentation
      foreach (Operation operation in context.WsdlPortType.Operations)
      {
          if (operation.Documentation != null)
          {
              OperationDescription operationDescription = context.Contract.Operations.Find(operation.Name);
              if (operationDescription != null)
              {
      operationDescription.Behaviors.Add(new WsdlDocumentationImporter(operation.Documentation));
              }
          }
      }
  }

The following code example shows how to configure the client metadata system to use the custom IWsdlImportExtension from an application configuration file.

<system.serviceModel>
    <client>
      <endpoint 
        address="http://localhost:8000/Fibonacci" 
        binding="wsHttpBinding"
        contract="IFibonacci"
      />
      <metadata>
        <wsdlImporters>
          <extension type="Microsoft.WCF.Documentation.WsdlDocumentationImporter, WsdlDocumentation, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />
        </wsdlImporters>
      </metadata>
    </client>
  </system.serviceModel>

Remarks

The ImportContract method is called when a contract is being imported. You can modify the contract or insert other exporting behaviors such as System.ServiceModel.Description.IServiceContractGenerationExtension and an System.ServiceModel.Description.IOperationContractGenerationExtension objects to modify the code that is generated for the contract.
